' OlL-PRESS CLOTH.

SPECIFICATION-forming part of Letters-Patent No. 372,110, dated October 25, 1887.

Application filed February 5, 1887. Serial No. 226,705. (No model.) 7

'To all whom, it may concern:

Be it known that I, THOMAS BENNETTS, of Brooklyn, in the county of Kings and State of New York, have invented new and useful In1- provements in Oil-Press Cloths, of which the .following is a full, clear, and exact description.

My invention relates to an improvement in press-cloths, and has for its object to reduce the cost of said press-cloths by effecting a saving of material and provide a cloth wherein less labor will be'required to remove the oilcake therefrom, and also wherein better re-' sults will be obtained in pressing the meal.

The invention consists in the construction and combination of the several parts, as will pointed out ing the fold out from end to end and the parts hinged together, and Fig. 4 is a plan view of the same opened.

It has been the practice heretoforein the construction of oil-press cloths to cut a strip of porous flexible material -such as canvasto a suitable length. One end is then folded over upon itself and the opposite end carried over upon the end thus folded, the meal being placed between the folded ends and the body of the cloth. Thus a cloth is obtained having two inclosed ends and two open sides. In this form of cloth, when heavy pressure is brought to bear upon the meal, the oil in forcing its way out at the ends is somewhat retarded in its action by the folded material and does not all pass through, leaving upon the edges of the cake at the'ends what isknown as an oilline. Again, in this form of cloth the inner folded end of the canvas becomes so embedded in the cake by the severe pressure that it is with the greatest difficulty and consumption of time that the cloth is disengaged from the said cake, and it frequently happens that the cloth is entirely destroyed in the operation.

It is the object of this invention to overcome these and other defects known to the trade. To thatend the cloth is constructed of a strip of porous flexible material, A'-such as canvas-which strip is folded centrally upon itself, so that the outer ends, a a, are parallel one above the other, as shown in Fig. 1. Centrally the strip A- in that portion which constitutes the fold a slit, B, is cut of any desired length, having the edges thereof loosely caught together by strong cord,b. The cording,however, may, if desired, be omitted. Thus a cloth is produced of two parallel layers of canvasone layer, O, at the bottom and the other, C, at the top of the meal--with three edges entirely open, and one, the folded edge, substantially open.

Instead of folding the canvas upon itself, as shown in Fig. 1, the canvas may be cut the desired length of the mat and united loosely at one end by loose overseaming or other suitable stitching, as illustrated in Figs. 3 and 4.

In operation, the cloth being opened, as shown in Figs. 2 and 4, the meal is placed upon the strip on one side of the slit B, a distance intervening between the outer edges of the mass and the edges of the lower layer, 0. The cloth is now folded, as shown in Figs. 1 and 3, and placed in the press. As pressure is brought to bear upon the cloth, the oil escapes freely, leaving the cake destitute of the oil-line and perfectly dry. By leaving a vent upon all sides a much better result is obtained, as will be observed, and by folding the cloth but once upon itself not only is a saving of material of at least six inches in length effected upon each cloth, which in the course of a yearrepresents thousands of dollars to mill owners, but the labor and time'of separating the cloth from the cake is greatly reduced, as the operators are enabled to readily grasp the edges, which in the old form of cloth become so embedded in the hard cake as to be extremely difficult to obtain a hold upon.

Having thus fully described my invention, I claim as new and desire to obtain by Letters Patent 1. An oil-press cloth consisting of two layers of substantially equal size folded upon each other and united to form a partially-open folded edge, substantially as described.

2. An oil-press cloth consisting of a strip of canvas folded once upon itself and the folded end provided with a slit, substantially as shown and described, and for the purpose herein set forth.

3. An oil-press cloth consisting of a strip of canvas folded once upon itself and provided at its folded end with a slit having its edges loosely united by a suitable stitch, substantially as shown and described, and for the purpose set forth.
